Definitions

  • An operating position select device for an automatic transmission of this kind is disclosed in Japanese patent laying-open publication (Tokkaihei) No. -323559 published as JP 9323559.
  • This select device includes a select lever unit disposed near a driver's seat in a passenger compartment and a mode shift unit mounted on an automatic transmission.
  • the select lever unit has a select lever manually operated by a driver and is connected with the mode shift unit by a connecting mechanism, such as a control cable, or a connecting linkage, which transmits an operating force applied on the select lever by the driver to the mode shift unit to shift operation modes of the automatic transmission.
  • This select device for an automatic transmission of this kind is disclosed in Japanese patent laying-open publication (Tokkai) No. 2003-97694 published as JP 2003097694.
  • This select device is, what is called, a shift-by-wire type one. It has a select lever manually operated by a driver, a select position detector for detecting a position of the select lever, a mode shift unit mounted on an automatic transmission for shifting its operation modes, an electric motor for driving a mode shift unit, and a control unit for controlling the electric motor based on an output signal from the detector.
  • the data of the reaction force map is rewritten based on at least one of the operating position, the operating velocity, an operating force applied to the select lever, and the assist force.
  • the operating position select device 100 includes a select lever unit 1 manually operated by a driver, an operating angle sensor 200 for detecting an operating angle of the select lever 2, a mode shift unit 300 mounted on the automatic transmission 19, a first and a second control cable 8 and 18 connecting the select lever 2 to the mode shift unit 300, an assist actuator 9 for assisting operating force inputted to the select lever 2 by the driver, an operating torque sensor 21 for detecting operating force applied to the select lever 2, and a control unit 22 for controlling the assist actuator 9.
  • the worm wheel 14 is provided on its upper surface with an electric terminal 24 contacting to a carbon resistor 25, indicated by a dashed line in FIG. 2, that is printed on a substrate fixed to a case of the assist actuator 9.
  • the electric terminal 24 and the carbon resistor 25 constitute the operating angle sensor 200 for detecting an operating angle of the select lever 2 to output an operating angle signal to the control unit 22.
  • the mode shift unit 300 shifts the operation modes of the automatic transmission 19 according to an operated position of the select lever 2.
  • the mode shift unit 300 has a manual plate lever 20 and a detent mechanism 350 for keeping the manual plate lever 20 in a position selected by the select lever 2.
  • the first control cable 8 rotates the coupling shaft 12, so that the terminal 24 on the worm wheel 14 united with the shaft 12 moves with respect to the carbon resistance 25 to change a relative angle between them.
  • This relative angle corresponding to an operating angle of the select lever 2, is detected by the operating angle sensor 200, which outputs an operating angle signal to the control unit 22.
  • the excessive movement prevention part 50 executes an excessive movement preventing process, and then the flow goes to step S11.
  • the excessive movement preventing process will be described in detail later.
  • the reaction force Fm acts on the select lever 2 against the operating force until the detent pin 29 reaches the peak of the cam 270 because the detent plate 27 united with the manual plate lever 300 is biased by the spring force of the spring plate 28 in a direction opposite to the operating direction.
  • the operating force for moving the select lever 2 in the operating direction needs to overcome the reaction force produced by the spring force of the spring plate 28, and the lever 2 moves with increasing the amount of deformation of the spring plate 28. This results in increasing the reaction force acting on the lever 2.
  • the spring plate 28 starts to reduce its amount of deformation with applying the spring force to the detent plate 27, so that the detent plate 27 is pressed to rotate so that the lever 2 is assisted to move forward.
  • the reaction force Fm increases in the lever-assisting direction, and then decreases until the detent pin 29 reaches the bottom of the cam 270 corresponding the R position.
  • This reversing characteristic of the reaction force causes affects a select feeling and/or an excessive movement of the select lever 2; the driver can hardly feel the select position and/or he or she moves the lever 2 so that it passes over the desired select position.
  • This excessive movement operation depends heavily on operating velocity of the lever 2; the possibility of the excessive movement increase with the operating velocity.
  • This operating position select device 100 of the first embodiment has many advantages described below.
